PACKAGE FOR HOUSING LIGHT EMITTING ELEMENT, LIGHT EMITTING DEVICE, AND LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a package for housing a light emitting element which suppresses fluctuations of light distribution of a light emitting device, which are caused by a difference in thermal expansion coefficients of a substrate and reflection members or the like.

SOLUTION: A package for housing a light emitting element includes: a substrate 1 having a mount part 1a of a light emitting element 4 on an upper surface; a frame-like first reflection member 2 attached to the upper surface of the substrate 1 so as to enclose the mount part 1a and having an inner peripheral surface serving as a first light reflection surface 2a; and a frame-like second reflection member 3 which is attached to the upper surface of the substrate 1 so as to enclose the first reflection member 2 having a gap 7 with an outer peripheral surface 2b of the first reflection member 2 and is provided with a second light reflection surface 3b at a position higher than an upper end of the first reflection member 2. This structure reduces stress generated between the reflection members 2, 3 and the substrate 1.
